'5 Claims.

The present invention relates to air conditioning attachments forautomobiles and similar vehicles, and has for its primary object toprovide a device of this character which. is detachably secured to thewindow of the vehicle and including a rotor arranged for partialsubmersion in. a receptacle containing water, and arranged to cause thepassage of air through the saturatedcan be installed in operativeposition upon the window of a vehicle without necessitating any changesor alterations in theconstruction thereof, and which is otherwise welladapted for the purpose for which the same is intended.

. Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which-- Figure 1 is aside elevational view of an automobile window showing the airconditioning attachment in position thereon.

Figure 2 is an end elevational view of the attachment showing the samemounted in position on the window.

Figure 6 is a fragmentary. sectional view of the discharge-throat, and

Figure 'l is a perspective view of one of the deflectors mounted in thethroat.

Referring now to th drawings in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention,the

' numeral 5 designates a casing generally which is closed at 'one end bya rear wall 6,-the other end ofthe casing having a'lower' front wall "Iand provided. with a funnel 8 above the front wall for admitting airinto the casing.

ported at its ends by the rear wall 6 and front wall 1, is a rod 9 uponwhich a rotor indicated generally at I 0 is mounted for'free rotation.The rotor is of generally cylindrical form and closed at its rear end bya rear end wall H, the side walls of the rotor being formed ofconcentrically 5 spacedforaminous material l2, preferably formed of wirescreening to form inner and outer walls and between which is positioneda loose filler l3, such as excelsior or the like. The front end of therotor is open and the inner end of the funnel 10 B is inserted into. theopen endthereof for admltting air directly into the interior of therotor. The end wall ll of the rotor is formed with an openingld throughwhich. the rod 9 is inserted for rotatably supporting 'the'rear end ofthe rotor 1| and adjacent the front end of the rotor and positionedbetween the inner and outer walls thereof is an annular spacing ring l5and to diametricalv ly opposite sides of which is secured the oppositeends of-a tubular member'lfi positioned trans-- 2o versely within therotor and having an opening 11 in its intermediate portion through whichthe rod 9 is also freely inserted to rotatably support the forward endofthe rotor on said rod. f

A longitudinally extending opening |8- is 25 formed in one of thesidewalls of thef-casing to form a discharge throat, the ends of theopening l8 being formed with extensions I9 and the top of the openingbeing formed with an extension 20 and cooperating withv the extension l9to form 30 a hood for the throat. The .bottom edge of the opening isprovided with a downturned lip 2| forming an inverted channel 22 withthe adjacent side wall of the casing and adapted to accommodatethe.upper edge of a window 23 of an 35 automobile or other vehicle body '24,whereby to support the casing upon the upper edge of said window withthe casing proper positioned outside of the window and the throat l8projecting into the interior of the vehicle, as' will be clearly ap- 4oparent from an inspection-of Figure 2 of the drawings.

A plurality of deflectors 25 are secured to the top of the casing bybolts 26, the deflectors being substantially of angle iron. formincluding the 45 flange 21 through which the bolt 26 are inserted at anintermediate portion of the flange whereby to pivotally support thedeflectors in the top of the casing. The deflectors extend transverselyof the casingwith their izmer ends overlying the upper surface of therotor, as clearly shown in Figure'3 of the drawings, and with theirouter i ends projecting through the throat and terminat- Extendinglongitudinally of the casing and suping at the open end thereof. Bypivotally adjusting the-deflectors on the supporting bolts 20, air

'throat ill for discharge into the vehicle.

discharged from the throat may be directed in a desired manner into theinterior of the vehicle. With the device mounted in position as shown inFigure 2 of the drawings, and with the funnel 8 positioned in a forwarddirection, the movement of the vehicle'will force air into the rotor l2and out through the side walls' thereof through'the The 'bottom of thecasing 5 is adapted to contain a suitable quantity of water in which thelower edge of the rotor is submerged, whereby the filler l3 will becomesaturated and as the air is forced through the saturated filler the samewill become cool by reason of the evaporation of the moisture therein.

In order to maintain all parts of the rotor in a moistened conditionsuitable means is provided for rotating the rotor upon the rod 9 whichincludes an endless cord 28 which has a portion wound once completelyaround the rotor as shown at 29 and separate flights of the cord '30 and3| are fed through tubular guides 32 positioned in the throat l8, thecord terminating in a loop 33 positioned on the inside of the window inconvenient position for manipulation by a person in a manner as will beapparent.

It is believed the details of construction and manner of operation ofthe device will be readily understood from the foregoing without fur-.ther detailed explanation.

Having thus described the invention, what I claim is;

1. An air conditioning attachment for vehicles comprising a casinghaving an air intakeopening at one end provided with an inwardly ex-="tending funnel and an air discharge opening in one side wall, saidcasing being adapted to contain a quantity of water, means for rotatablysupporting a porous rotor at one end and at an intermediate portion in apartially submerged condition in the casing said funnel projecting intothe rotor at its other end and means for supporting the casing on theupper edge of a window of the vehicle.

2. An air conditioning attachment for vehicles comprising a casinghaving an air intake opening at one end provided with an inwardlyextending funnel and an air discharge opening in one side wall, saidcasing being adapted to contain a quantity of water, meansfor rotatablysupporting a porous rotor at one end and at an intermediate portion in apartially submerged porting the casing on the upper edge of a win-' dowofthe vehicle and means for rotating the rotor.

3. An air conditioning attachment for vehicles comprising a casinghaving an air intake opening at one end provided with an inwardlyextending funnel and an air discharge opening in one side wall, saidcasing being adapted to contain a quantity of water, means for rotatablysupporting a porous rotor at one end and at an intermediate portion in apartially submerged condition in the casing said funnel projecting intothe rotor at its other end, means for supporting the casing on the upperedge of a window of the vehicle and flexible means for manually rotatingthe rotor.

4. An air conditioning attachment for vehicles comprising a casinghaving an air intake opening at one end and an air discharge opening inone side wall, said casing being adapted to contain a quantity of water,means for rotatably supporting a porous rotor in a partially submergedcondition in the casing, means for supporting the casing on the outsideof the vehicle with the-discharge opening inwardly thereof and flexibleoperating means for the rotor including a circumferentially extendingportion surrounding the rotor and an operating end extending into thevehicle. a

5. An air conditioning device for motor vehicles comprising a casingprovided with an outlet passage along one side thereof for fitting awindow opening of a motor vehicle, said casing having an open forwardend, a funnel shaped member mounted in said end and extending inwardlythereof, a drum rotatably mounted in said casing and having an openforward end communicating with the inner end of said funnel member, saiddrum having an absorbent porous annular wall, a pan formed in the bottomof said casing for containing water and into which a portion of saiddrum extends, the forward end of said casing extending toward the frontof the vehicle whereby air will be directed inwardly through said funnelshaped member and into the drum during the forward motion of thevehicle, and means for rotating said drum for moistening its porous wallto cool and cleanse the air passing through said wall to said outletpassage.
